Plant Parasites of Europe

leafminers, galls and fungi

Delia florilega

Delia florilega (Zetterstedt, 1845)

mine

Primarily a borer in the stem and petiole, but the larva can make corridor-like excursions into the blade. Perhaps the mines can be distinguished from those of Botanophila fugax by Delia mines harbouring several larvae, Botanophila mines just one (Robbins, 1991a). Neither larvae nor mines can be distinguished from those of D. platura and Pegomya flavifrons.

Brassicaceae, Caryophyllaceae; polyphagous

Brassica; Cerastium; Spergularia.

From Scandinavia to the Iberian Peninsula and Italy, and from Ireland to Poland and Hungary; also large parts of European Russia (Fauna Europaea, 2007).
